I’ve been a big fan of Saint Francis of Assisi and this is one of the greatest movies about him.
Adding to this are the two of my favourite books in the same lines:-
The practice of the Presence of God by Brother Lawerence and The Imitation of the Christ by Thomas Kempis
St’ Francis of Assiss , his prayer only taken for
" Twin heart Meditation" 
I’ve had fantastic experience with Padre Pio after I visited his shrine in Ontario Canada. Especially with guardian angels, padre pio had a special relationship.
